ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 623,936, dated April 25, 1899.

Application filed April 12, 1898.

To all whont it may concern:

Beitknown that I, WILLIAM H. WINELAND, a citizen of the United States, residing at Easton, county of Northampton, Pennsylvania, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.

My invention belongs to that class of rotary engines in which the rotary piston carries a series of sliding plates or blades which are brought in succession by the rotation of the piston to receive the impact of the steam.

It is my object to simplify the construction of engines of this class, to cheapen the manufacture, and to secure the maximum degree of efficiency in action.

My invention includes the features of construction hereinafter pointed out, and it also includes the special arrangement of parts by which I am enabled to compactly arrange a pair of pistons side by side in the same casing, thus providing an engine of compound form.

In the drawings, Figure 1 is a side view of the invention with parts in dotted lines. Fig. 2 is a bottom plan View of the cover. Fig. 3 is a section on line 3 3 of Fig. 1.

The double cylinder comprises the heads 1 2, the central partition 3, and the rings 4 5 between the heads 1 and 2, respectively, and the partition 3, said rings having flanges 6, bolted to the heads 1 and 2 and to the partition, as at 7. WVithin the cylinders 8 and 9 thus formed pistons 10 and 11 are arranged to rotate, being fixed for this purpose to the shaft 12, extending through the casing. These pistons have annular depressions in. their sides at 13 about the shaft to receive laterally-projecting cams 14: on the inner faces of the heads and upon opposite sides of the partition. The pistons also have flanges l5, fitting snugly against the inner walls of the cylinders. Each piston has four radial slots 18, cut through the flanges and into the body part of the piston, in which the sliding blades or plates 16 move out and in, and the ends of said blades, as at 19, extend laterally over the peripheries of the cams on the heads and the partition.

At the top, as shown in Fig. 1, the cylinder has an extension 20, surmounted by a coverplate 21, in which inlet and exhaust ports 22 Serial No. 6 '7 7.3 5 1' (N0 model.)

are formed. This cover-plate also carries the fixed abutment 23 midway between the ports, which interrupts the steam-space and extends down to the periphery of the piston at 24 within the piston-flanges. This abutmentis formed in one with the cover-plate and with the outer cam-plates 25, which have their lower edges curved, as at 26, dotted lines, Fig. 1, to correspond to the curved low part of the upper surface of the fixed cams 14. The camplates 25 are adapted to fit, as shown in Fig. 3, within the flanges of the pistons and engage the outer ends of the sliding blades or plates. In Fig. 3 one of these plates is shown in its innermost position in the right-hand cylinder, while in the left-hand cylinder the plate is shown in its outward position.

Supposing the engine to be taking steam through the right-hand port in Fig. l, the piston would rotate in the direction of the arrow, the steam acting upon the blades as they are pushed out until the maximum effect is reached at the point y in Fig. 1. The blades then remain out until the point acis reached, when the steam begins to exhaust through the space z and the left-hand port 22. The blades begin to recede into the slots of the piston at the point at, so that when they reach the abutment they are all the way in and pass by said abutment. The engine may be reversed by introducing the steam through the left-hand port 22.

I claim 1. In combination in a rotary engine, the flanged piston carrying the sliding plates, the cams extending into concentric recesses in the sides of said piston for forcing the blades outwardly and an outer cam fitting down within the flanges of the piston to engage the sliding plates.

2. In combination in a rotary engine, the flanged piston having concentric recesses in its sides, the cylinder, the sliding plates carried by the piston, the inner cams carried by the casing and extending into said recesses, an outer cam fitting down within the flanges of the piston, said flanges extending between the outer cam and the heads of the cylinder, substantially as described.

3. Incombination, the heads, the partition between them having the laterally-project ing cams, the flanged rings between theheads and the partition, the pistons having concentric recesses in their sides to receive the cams and having the sliding blades with their ends extended over the edges of said cams, the flanges of said pistons fitting the inner surfaces of the rings and the cover-plate having cams extending down within the flanges 0f the pistons with a transverse abutment extending down between the cams, substantially as described. IO

In testimony whereof I affix my signature in presence of two witnesses.
